This invention relatesto assembling inachines, and more particularlyto self-levelinglavatory assemblingamachines.

Tlhe lav-stories and pedestals are made separatelyand as the lavatories are-usually warped a little as they'coine from the lrilns, care has to be taken to level each lavatory with respect to the corresponding pedestal to assure proper final assembly ithereof. Preferably such leveling is efiected by'forrn- .aa seat. of plastic material such as plaster Paris on each lavatory before shipping from the factory sothat When .the lavatorytand pedestal are tinallyassembled position for use, the lavatory will be in proper leveled positionron the pedestal. The seatonaeach lavatory is torinedby placing the lavatory and the corresponding pedestal in proper relative position, filling the space between them with -.the plastiomaterial and after permitting the plastic material to set, removing the pedestal from the seat thus formed. The lavatory and pedestal are then transported =01 shipped as separate parts ready for assembling. So far as I am aware,

theu orlr of forming such-seats on the'lava tory has heretofore been done entirely by hand.

The main-object of my invention is toprovide :a-inachinc .whereby pedestals and lavatories oiubowl portions maybe readilypositioned for the formation,oi' such seats of plastic materialcand with a saving of labor.

A further object of theinvent-ion is to provideaneans -.xvher.eby the height of each assembled lavatory and pedestal may he definitelyl determined. 1

.leys 10 and 11 at the top of the frame and they pass around pulleys 16 and downwardly to a treadle 17 to which they are connected. When it is desired to have the arms 6 swing downwardly, the operator steps on the treadle 1? and raises the counterweights.

After the pedestal 2 has been placed in the apparatus, the lavatory 15 in inverted position is brought into proper position relative to the pedestal. This is effected by placing the lavatory on cross bars 18 supported by and balanced on a central cross bar 19, and lifting the lavatory by means which include levers 20 at opposite sides of the frame to which the levers are pivoted intermediate of their ends, and rods 21 connected at their lower ends with said bar 19 by means including springs 22 interposed between the lower face of the beam or bar 19' and suitable stops 011 the rods 21. At their outer ends the levers 20 are provided with pivoted pawls 23 adapted to engage teeth in racks 24 fixed on the frame and to hold the levers 20 in a position to support the lavatory 15 in leveled position against stops 25 in the form of screws threaded in brackets 26 supported in slots in fixed brackets 27 on the frame. The stops 25 may be adjusted in proper leveling position by use of a level and the springs 22 may be compressed to the desired degree as determined'by the extent to which the outward ends of the levers 20 are Preferably the machine is operated in the following manner:

The operator steps on the treadle 17 and raises the counterweights 13, thereby permit-- tingthe arms 6 to swing downwardly. A pedestal 2 in inverted position is then inserted with its base adjacent the plate 5 and the treadle is released. The counterweights 13 then cause the arms 6 to be swung upwardly and the balls 8 engage the pedestal on opposite sides and press it upwardly against the plate 5. Usually the pedestals are substantially square in cross section. A

' lavatory 15 is then placed in inverted position on the crossbars 18 and the operator forces down the outer ends of levers 20 until the four corners of the lavatory engage the adjustable stops or screws 25 which have already been leveled.

hen the firstpedestal and lavatory have been inserted, the vertical positionof the pedestal is adjusted by means of the screw 1' to give the'desired space for the plastic material or plaster Parisbetween the pedestal and lavatory. After this adjustment has been made for the first lavatory and pedestal, no further adjustment need be made unless and lavatories.

After the plastic material has been inserted between a pedestal and lavatory and allowed to set, the levers 20 are swung downwardly sufficiently to release the pawls 23 and are then permitted to swing in the opposite direction to lower the lavatory and permit the removal thereof. The pedestal may be released b stepping on the treadle 17 and may then be removed from the machine. it i As will be evident from the scope of the appended claims, various changes in the details of construction may be made without departing from the spirit of my invention.
